Inclinometry Output Format

Inclinometry Output Format


In March 1999 the inclinometry data acquisition system was expanded to read in not just the 3 channels (X,Y,T) from each of the three original inclinometers (T, L and R), but also the 3 channels from the Spare inclinometer, located at that time on one of the radial arms, plus data from two strain gauges (G1, G2), measuring loads on the track at (true) azimuth ~56 degrees, or under the middle of track segment #6.

This gives 14 output channels, explicitly :

   Ch #   1   2   3   4   5   6   7   8   9  10  11  12  13  14
    aka   1   2   3   4   5   6   7   8   9   A   B   C   D   E
         TX  TY  TT  LX  LY  LT  RX  RY  RT  SX  SY  ST  G1  G2

Unfortunately, there are an extraordinary number of additional spaces tagged onto the end of the data lines that make offline editing necessary before processing can begin. Do this :

            sed -e 's/..........//g' incfilename.dat > outputfilename.dat

(where the 10 ...'s are really 10 spaces). (And delete the last line of data (phoney - taken at a 'park position of az=177.77)).

The incred software on the summit VAX, and the partial mirror in my Hilo unix account (/home/imc/pointing/progs) is then compatible with this data file structure.
